Post Modern Principals- Reaction

In reaction to this article, I have little to say.
What I do have to say, is why attempt to define art? To say something has certain principles behind it, is simply to give something a plain, boring, textbook meaning. This argument has a lot to go with my previous post, Art without Meaning. As the way I see it, the more one attempts to get someone to put art in an educational light, the less power the art has. To define things such as juxtaposition, text, net art, and otherwise, would be less principles, than simply methods. To me, a principle is a standard or guideline, while these, are simply common themes that one can spot throughout many pieces of artwork.
